Grom HPLC Columns
The German manufacturer Grom (part of Dr. Maisch) produces HPLC columns for highly efficient and fast chromatography. With the comparatively short NovoGROM columns, a significantly higher sample throughput is possible. Various GromSil phases are available, including eight different C18 and six different C8 phases. Furthermore, Grom offers HPLC columns for amino acid analysis.
Here you can find more information about GromSil phases.
NovoGROM low-dispersion, high speed HPLC columns
The comparatively short NovoGrom columns enable highly efficient and particularly fast chromatography. You can choose between capillary columns, microbore columns, analytical, semi-preparative and preparative columns with different inner diameters.
GROM SIL Phases
GromSil phases are characterized not only by high chemical selectivity, but also by their excellent physical properties: they are absolutely spherical, completely porous and have a high specific surface area. As a result, GromSil-packed columns exhibit excellent flow properties (e.g. low backpressure) as well as particularly high efficiency and peak symmetry.
Eight different SIL-ODS phases and six different SIL-Octyl phases have been developed to offer the widest possible range of selectivities, which are excellent even for complex separations.
GROM SIL C18 phases
Typical fields of application are the analysis of fat-soluble vitamins, peptides or proteins as well as the analysis of herbicides,
fungicides, bacteriocides or pesticides.
The phases are also suitable for the analysis of drugs such as antibiotics or antihistamines or barbiturates.
| GROM-SIL 100 ODS-0 AB | High-quality phase with special endcapping for the outstanding separation of acids and bases. |
| GROM-SIL 100 ODS-1 PE | Economical phase with partial endcapping and high selectivity. |
| GROM-SIL 100 ODS-2 FE | Fully endcapped stationary phase with outstanding selectivity for most applications. |
| GROM-SIL 120 ODS-3 CP | Encapsulated, chemically stable phase with metal-free silica gel matrix. |
| GROM-SIL 120 ODS-4 HE | High resolution - a new hydrophylic endcapping makes this phase especially suitable for peptides. |
| GROM-SIL 120 ODS-5 ST | Standard phase for practically all applications. |
| GROM-SIL 120 ODS-6 NE | ODS phase for special applications. High hydrophobicity despite the absence of endcapping. |
| GROM-SIL 80 ODS-7 pH | Polymer-coated, pH-stable phase with extremely high carbon-content. |
GROM SIL C8 phases
The phases are used for the analysis of peptides, proteins, nucleotides, basic compounds (amines, etc.), fatty acids (phenacyl derivatives) or angiotensins.
Other fields of application include the analysis of drugs such as antihistamines.
| GROM-SIL 100 Octyl-1 B | Base-deactivated phase with enhanced selectivity. |
| GROM-SIL 100 Octyl-2 AB | Acid- and base-deactivated phase specially suitable for the separation of acids and bases. |
| GROM-SIL 120 Octyl-3 BA | Tailor-made for the separation of basic molecules, monomeric bonding of alkyl silanes with differing chain lengths. |
| GROM-SIL 120 Octyl-4 FE | Fully endcapped octyl phase, “monomerically bound” and thus highly versatile. |
| GROM-SIL 120 Octyl-5 CP | Octyl-phase on silicone-encapsulated particles, particularly long lived. |
| GROM-SIL 120 Octyl-6 MB | Densely coated C8 phase, endcapped, for acidic and basic compounds. |
